Tel: 781.329.4700 Fax: 781.461.3113 www.analog.com Evaluation Boards for the AD62x Series and the AD822x Series Instrumentation Amplifiers FEATURES EVAL-INAMP-62RZ (SOIC or PDIP) The EVAL-INAMP-62RZ is designed for evaluation of 3 generic, easy-to-use evaluation boards instrumentation amplifiers in the legacy pinout. This board Shipped with an assortment of Analog Devices, Inc., in-amps can be used to evaluate the AD620, AD621, AD622, AD623, Solder in the in-amp to be tested Test pins already populated AD627, AD8223, and AD8225 instrumentation amplifiers. In Decoupling capacitors already populated addition to the basic in-amp connection, circuit options enable EVAL-INAMP-62RZ board the user to adjust the offset voltage, apply an output reference, Compatible with AD620, AD621, AD622, AD623, AD627, or provide shield drivers with user-supplied components. The AD8223, and AD8225 in SOIC or PDIP board is shipped with an assortment of instrumentation amplifier EVAL-INAMP-82RZ board ICs in the legacy SOIC pinout, typically AD620, AD621, AD622, Compatible with AD8221, AD8226, AD8227, AD8228, AD623, AD8223, and AD8225. The board also has an alternative AD8229, AD8421, AD8428, and AD8429 in SOIC package footprint for a through-hole, 8-lead PDIP. EVAL-INAMP-82RMZ board EVAL-INAMP-82RZ (SOIC) Compatible with AD8220, AD8221, AD8226, AD8227, The EVAL-INAMP-82RZ is designed for evaluation of AD8228, AD8236, and AD8421 in MSOP package instrumentation amplifiers in the high performance pinout. This board can be used to evaluate the AD8221, AD8226, AD8227, AD8228, AD8229, AD8421, AD8428, and AD8429 in SOIC packages. The board is shipped with an assortment of instrumentation amplifier ICs in the high performance SOIC pinout, typically AD8221, AD8226, AD8421, AD8428, and AD8429. The evaluation board is arranged so that users can easily solder on the gain resistor. The in-amp reference pin can be connected to ground through a solder short or connected to the users source through the test pin. A small prototyping area allows interfacing to another part in an SOIC package. Users can add their own SMA or SMB connector to interface the evaluation board with complementary tools, such as an Figure 1. analog-to-digital converter (ADC) evaluation board, available GENERAL DESCRIPTION from Analog Devices. This user guide describes three generic evaluation boards that EVAL-INAMP-82RMZ (MSOP) can be used to evaluate many of Analog Devices instrumentation The EVAL-INAMP-82RMZ board is exactly the same as the amplifiers. For information on the performance of a specific EVAL-INAMP-82RZ board, except that is designed for the instrumentation amplifier, see the data sheet for that MSOP pinout. This board can be used to evaluate the AD8220, instrumentation amplifier. AD8221, AD8226, AD8227, AD8228, AD8236, and AD8421 in MSOP packages. The EVAL-INAMP-82RMZ board ships with an assortment of in-amp ICs in the high performance MSOP pinout, typically AD8220, AD8221, AD8226, AD8228, and AD8421.
